Visualization of nanodiamond formation in molten carbon under pressure

We discuss the characteristics and visualization of simulations of nanodiamond clusters grown from molten carbon. The general trends of nanodiamond size and quality as functions of growth conditions resemble those found experimentally. In particular, the probability of finding nanodiamonds, and their quality increased wth increasing sample density and cooling rate. We also discuss finite size effects and possible phase transitions within molten graphite.
